BoLsTER FoR HoPPER-QARS.

SPECIFICATION forming part of Letters Patent No. 720,246, dated February 10, 1903. Application filed June 9,1902. Serial No. 110,785. (No model.)

Beit known that I, JOHN M. HANSEN, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Bolsters for Hopper-Cars; and I do hereby declarethe following to be a full, clear, and exact description thereof.

My invention relates to metallic railwaycars, and more especially to a body-bolster construction adapted to hopper-cars having inclined floors. Y

The improvement consists in the details of construction hereinafter described and claimed.

l In the accompanyi ng drawings, Figure 1 is a car, showing the floorplates partly removed. Fig. 2 is a transverse section of the car on the line 2 2, Fig. 1.- Fig. 3 is a central transverse section of the body-bolster; and Fig. 4 is a section on the line It 4, Fig. 2.

My invention is shown applied to a hopperbottom car having inclined licor-plates 1, side plates 2, and center sills 3. The type of car illustrated has no side sills as such; but the side plates 2 are secured to each other by means of trough-shaped stakeslt and are provided with the top angle-rails 5, bottom anglerails 6, and vertical stiffeners, (not shown,) so as to form, in effect, plate-girders which assist in supporting the load.

The improved bolster comprises a tension member composed of two hanged bars 8, preferably angle-bars, extending transversely of the car from side to side and lying just above the center sills, a compression member comprising, preferably, a ilat plate 9, extending underneath the center sills toward the sides of the car, and web-fillers 10, one on either side of the center sills and composed of llat plates suitably secured to the tension and compression members. These plates preferably are tapered from the center sills outwardly, as shown, and they are connected to the tension member by having their upper edges project between the vertical flanges of the bars 8, comprising the tension member, and riveted therebetween. They are secured to the compression member by having anglebars 12 riveted to the lower edges thereof, one on either face thereof, to the horizontal flanges 'ing inwardly, and

Awardly-projectin g of which angle-bars the cover-plate 9 is riveted. The center sills are channel-shaped structures, such as the rolled channel-beams shown with their flanges preferably projectthe horizontal flanges of the bars 8 rest on and are riveted to the top flanges ofthe center sills. Between the center sills in line with the bolster members is the center brace 13, preferably of cast metal, provided with anges whereby it is riveted to the center sills and provided with a central boss 14, having a vertical opening for receiving the center pin. The center bearing-plate 15 and side bearings 16 are riveted to the cover-plate 9.

Suitably secured to the bolster is a Afloorsupport 18, which preferably is a flat plate, as shown, provided at its upper edge with the inclined flange 19, upon which the floor-plates 1 rest and to which they are secured. This plate 18 can conveniently be secured to the bolster by having its lower edge riveted between the vertical flanges of the bars S.

The bolster is secured to the center sills by means of short sections of angle-bar 20, riveted to the inner ends of the web-plates 10 vand to the center sills. They are connected to thesides of the car by means of sections of angle-bar 21, which are riveted to the ends of the plates 10 and 18 and have their laterally projecting flanges riveted to the side plates of the car. Extension-plates 23 are' riveted to the lower faces of the angle-bars 12 and project outwardly beyond the ends of the bolster to form brackets for supporting the sides of the car and to which brackets the outflanges of the bottom anglerails are riveted.

This construction of bolster requires the makingof no special shapes, b ut is built up entirely of at plates and rolled commercial steel, and the parts are so assembled that all of the rivets can be driven by machinery, thus greatly decreasing the cost of assembling the same.

What I claim as my invention, and desire to secure by Letters Patent, is- 1. In a metallic car, the combination with a center sill, of a body-bolster comprising two web-plates one on either side of the center sill, a flanged bar secured to the upper edges of said plates and lying above the center sill IOO and comprising the tension member, a compression member secured to the lower edges of said web-plates and extending continuously underneath the center sill, and a floorsupport secured to said bolster and projecting vertically upward and secured to the floor. 2. In a metallic car, the combination with the center sill, of a body-bolster comprising two web-plates one on either side of the cenro ter sill, a flanged bar secured to the upper edges of said plates and lying over the center sill and comprising the tension member, a compression member secured to the lower edges of said web-plates and extending un- 15 derneath the center sill, and a floor-support secured to said bolste and projecting upwardly and having a flange on its upper edge to which the floor-plates are secured.

3. In a metallic car, the combination with zo the center sill, of a body-bolster comprising two web-plates one on either side of 'the sill, a pair of flanged bars secured to the upper edges of said plates one on either side thereof and extending over the center sill and 25 comprising the tension sion member secured to the lower edges of said web-plates and extending underneath the center sill, and an upwardly-projecting plate having its lower edge riveted between 3o the bars comprising the tension member and serving as a support for the floor. 4L. In a metallic car, the combination with a centersill, of a body-bolster comprising two l web-plates one on either side of the center sill, a compression member secured to the lower edges of said plates and extending; underneath the center sill, a tension member comprising a flanged bar having its v5 rtical flange secured to the upper edges of saf( .webplates and having its horizontal flange lying upon and secured to the center sill, and an upwardly-projecting plate having its lower edge secured to the bolster and serving as a floor-support.

5. In a metallic car, the combination with a center sill, of a body-bolster comprising two member, a compresweb-plates one on either side` of the center sill, a flanged bar secured to the upper edge of said plates and extending over the center sill and comprising the tension member, a compression member secured to the lower edges ot' said web-plates and extending underneath the center sill, an upwardlyprojecting plate having its lower edge secured to the bolster and serving as a floor-support, and vertically-arranged angle-bars secured to the ends of the web-plates and said extension-plate and serving as a means for securing the side plates of the car thereto.

In testimony whereof I, the said JOHN M. 6o HANSEN, have hereunto set my hand.

JOHN M. HANSEN.
